Application filed May 18, 1917. Serial No. 169,396.

To all whom it may concern:

Be it known that I, HANS I. E. PETERSEN, asubjeet ofthe King of Norway, and a resident of Fond du Lac, in the county of Fond du Lac and State of lVisconsin, have in vented a new and Improved Motor-Starter, of whichthe following is a full, clear, and exact description.

This invention relates to motors and par ticularly to an improved device for properly starting a kerosene motor, and has for an object the provision of an improved construction whereby the kerosene may be prop erly vaporized on the first compression so as to immediately explode.

Another object in view is to provide an of cylinder head With a heating chamber and means for independently heatin part of the heating chamher so as to pro uce a proper gasifying of the oil at the time and immediately previous to the time of ignition.

In the accompanying drawing Figure 1 is a longitudinal vertical section through a cylinder head disclosing an embodiment of the invention.

Fig. 2 is a side view .of a heating core embodying certain features of the invention.

Fig. 3 is a top plan view of a heating sleeve'or drum. v In explosive engines using a light oil, as for instance, gasolene, an explosion may be. secured quickly by reason of the rapidgasifying of the gasolene when properly carbu-' reted and drawn in and compressed. However, ,when a heavier oil, asfor instance, kerosene is used in the explosive engine it is necessary to the parts in some manner in order to produce a proper explosion. Heretofore it has been customary to use gasolene or other light oil for starting kerosene motors and running the motors until the parts have become sufficiently heated to allow the use of kerosene. According-t0 the present invention means have been provided for heating certain parts of the cylinder head whereby no gasolene or other light ine may be started instantly.

Referring to the accompanying drawin by numerals 1 indicates a. cylinder hea which in general outline may be of any suitable kind and connected with any suitable structure or cylinder, head 1 being provided with n inlet and an exhaust of some kind. The special construction of head 1 includes a a further breaking up.

heat the cylinder and certain of fuel is necessary and yet the en-" projection 2 having a bore 3 andv an offset threaded portion-4 for receiving the cap 5 which is threaded into the offset portion 4. Thecap 5 is provided with an opening 6 for receiving a spark plug 7 formed with an annular extension 8 having a beveled overhanging portion 9 for fitting against the beveled upper edge of the heating sleeve 10.-

The heating sleeve or drum 10 fits into an annular recess or ofl'set portion from bore 3, as shown in Fig. 1, so as to rest upon the annular shoulder 11 and to be pressed tightly into position by The sleeveor drum 10 ispreferably made the annular extension 8.'

.from some easily heated material which transmit the heat, as for instance,.brass. In forming thisdrum an annular orperipheral part 12 is provided connected by transverse partitions 13 and 14 extending entirely across the drum and merging into eachother at the center, as shown Fig.3, whereby four passageways 15, 16, 17 and 18 are provided. 1

Each partition is provided withan ofiset or shouldered portion 19 and apertures 20 extending;- from the shoulder diagonally through the partition, as shown in Fig.- 1, whereby during the compression stroke the fumes of the oil will pass up passageways 15 to 18 inclusive, and will strike against these. shoulders where it is broken up more or less and some'caused to pass through the apertures 20 for producing will quickly be heated so that any of the particles striking the same will be gasified thoroughly by through the The drum 10 is to the heat absorbed so that the gasified fuel compressed in the space 21 near the spark plug 7 will provide ample gas for producing an explosion.

In order to heat the drum or sleeve 10' 'before the engine is started so as to cause an immediate explosion as soon as the engine is turned over, heating cores 22 and 23 are provided, said cores extending through apertures 24 and 25 in the extension 2, the inner part of the" cores having a curved shaped face 26, as shown in Fig. 2, so as to fit snugly against the drum 10 and transmit heat thereto. These cores may be of brass or other suitable materlal. Each core is provided with a.

beveled portion 27 which coacts with the beveled portion of the respective nuts 28- and 29 whereby the cores are clamped tightly in position and an air-tight connection probrri nection at this'point and producing an airtight connection by the annular extension 8 insures against any loss of gas at any time; T he outer part of the cores 22 and 23 have connected thereto in an suitable manner heating coils 30 and 31 which are to receive current from any suitable source (not shown) and which may be turned off or on at any time.

Usually when it is desired to start the engine both coils 30 and 31 are supplied with current and heat is transmitted therethrough from cores 22 and 23 and from said cores to the drum 10. From drum'lO the surrounding parts of the extension 2 and cap 5 will be heated to a certain extent. This heat is maintained as long as desired,.preferably a comparatively short time, and then the engine is turned over, whereupon the kerosene vapor is drawn in and compressed in the extension 2, and by reason of the heat there in, and especially in drum 10, it will become gasiiied and thereby easily ignited. It is of course understood that not all of the gas is compressed into the extension 2, but sufficient for the purpose desired, as said extension and associated parts may be of any desired size in comparison with the cylinder. After the engine explodes and starts to running it is preferable to turn off one of the heating coils as a less heat will be sufiicient, though it is desirable to have at least one coil continually in use for some time or until the regular explosions have heated the cylinder and cylinder head sufficiently to insure I a *proper gasifying of the carburetor kerosene. It will be understood that the construction is such that any motor operated with crude oil or any oil or fuel can easily be started.
